One of the most requested features on Microsoft's UserVoice forum was the Support for Dynamic '+' Email Aliases in Office 365. This has been pending since 2017 and Microsoft finally implemented it in September 2020. Woohoo! However, it's not enabled by default in Exchange Online, so we'll have to turn it on.
By default, all SharePoint sites created in SharePoint Online are set to the United States time zone and locale. In the past, you had to either manually or programmatically set the timezone, region and locale for every site including all sites generated by the creation of an Office 365 group.
We've recently enforced MFA for admin accounts that connect to Exchange (and other O365 Services). This means that in order to connect via PowerShell we need to install the Exchange Online PowerShell module.
I work in a UK based company and we've recently been using Microsoft Teams more and more, which for the most part has been great. However, whenever someone edits an Excel workbook within the Teams web (or desktop) app, they realise that datetime values are in the US format (MM/DD/YYYY). This seems to happen even if they have previously set the regional settings to UK in SharePoint / Office 365. If you haven't yet set the regional settings for the Office 365 group's SharePoint site, then you should do that first. If you have then you can skip this step.
If you've used SharePoint Online before you've probably come across some of it's limitations. Of course you can store up to 30 million items or file in a SharePoint list but if a list view shows more than 5,000 item then you will probably see a nice error either in the web UI or from console if you use any of the SharePoint tools.
